	  SIDs for domain users and groups to 31-bit uids and gids, respectively.
	  This plugin also implements the nss_info API and can be used
	  to support a local name mapping files if enabled via the
	  "winbind normalize names" and "winbind nss info"
	  parameters in smb.conf.

		    Mapping of both user and group names is supported.
